Abstract

The invention discloses a sealing device of charging and discharging ends of a rotary cylindrical type device. The sealing device comprises a rotary sleeve and a fixed sleeve, wherein the fixed sleeve is sleeved outside the rotary sleeve; the rotary sleeve is fixedly connected with a movable supporting ring; the outer end surface of the movable supporting ring is fixedly connected with a movable friction block; the peripheral surface of the fixed sleeve is provided with a static supporting ring which is movably sleeved on the fixed sleeve; the static supporting ring comprises a cylinder body and an inner side plate which is fixed on the cylinder body; the inner end surface of the inner side plate is fixedly connected with a static friction block which is adaptive to the movable friction block; the static supporting ring is provided with a plurality of uniformly distributed pressing mechanisms for the movable friction block and the static friction block; each pressing mechanism comprises a lever; one end of each lever is pressed on the outer end surface of the inner side plate of the static supporting ring; the other end of each lever is connected with an extension spring; the supporting point of the lever is arranged on a lever seat; the lever seat is fixed on the fixed sleeve; and the extension springs are connected to the charging and discharging ends of the device. The sealing device provided by the invention has the advantages that the sealing effect is good, the service lives of key components are long, and the operation rate of the device can be improved.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for the inlet and outlet ends of rotary drum equipment. Background technique [0002] The inlet and outlet sealing devices of rotary kiln and dryer and other rotary drum equipment used in metallurgy and cement industry are basically divided into two types, namely radial seal and end face seal. At present, the radial seal mainly adopts the lamination structure, and its disadvantage is that the lamination wears relatively large, and the lamination and its corresponding accessories do not need to be machined, and the sealing effect is poor. The world famous cement machinery design company Denmark Smith uses this kind of structure. At present, the end face seal mainly adopts the friction plate structure. The dynamic and static friction plates of this structure need to be machined, and its sealing effect is better than that of the laminated plate structure. The famous cement machi...
